added files for the ExpParetoChurnModel
updated file list & Makefile for the additional files
updated churn.ini for the new ExpParetoChurnModel with setting for
ComNets paper of Mathias
minor change to the parameter in churn.ini
disabled the check for non-zero value of b in Pareto departure of the
ExpParetoChurnModel
adapted the e1212 underlay
updated file list
read parameter for the arrivalRate from the NED file
introduced the hopCount variable in the VideoChunk packet
new field: overlayHopCount for the VideoChunkPacket
variables and getters for collecting delays (end-to-end & overlay hop
count) at the VideoBuffer
reset overlayHopCount at the ChunkGenerator
trigger the functions to collect delay differences from the local buffer
to the global statistic module
new signals and interface to collect and report delays
separated the timestamp field into two fields originalTimestamp (time
when the video chunk was generated) and sentTimeStamp (time when the
video chunk was sent from a remote peer)
fixed the calculation of end-to-end delay using the sentTimeStamp
modified the code to initialize the originalTimeStamp in accordance with
the change in the name of the variable
fixed at the DonetStatistic module, when there is nothing record 0 for
end-to-end delay and overlayHopCount instead of -1
added signals and code to record end-to-end delay and overlayHopCount
locally
changed the name of the metric EndToEndDelay into DelayOneOverlayHop
